轴类零件通用有限元程序的研制

立足于微型计算机作有限元分析。考虑到轴受空间力系的作用,注意到对弹性约束和给定位移约束的处理,研制了轴类零件通用有限元程序,仅使用一个数组管理所有信息,并采用了三级复盖技术。用很少的内存,在很短的时间就可以对轴类零件进行有限元分析,计算出轴的刚度、强度、自振频率及振型。

Based on microcomputer analysis on the axle affected by force group in space was done with finite element method while disposal of elastic restraints and bit shift restraints given was concerned. From here a general purpose program was put forward for the calculation of axle parts. In the program only one array was used for supervising all of information while three-grade overlay technique is taken. So analysis on an axle part and calculation of the stiffness, strength, auto-oscillation frequency and oscillation pattern of the axle can be done but only little time and less internal storage is needed.
